I want to share my code review experience with the projects that I worked (officially and the ones here in Collaborizm). First and foremost, code review is very critical and can never be neglected. It applies even if a single person or freelancer is working on a project. Building code is not fun (Unless one knows what exactly they are doing :)). Imagine, you are coding a crazy copy paste driven code which nobody understands, then you cannot expect others to code on that project. Code review brings in the below high level benefits like

Well structuring of code as per the industry or organization standards

Peer code review helps within the team to understand and can work together as a team.

Early bug detection

Lots of code improvements comes after the review. An open minded approach to re-factor code helps the organization to maintain code for the long run.

Freelanced based projects are missing these critical aspects. I would highly recommend each one of you to understand the need for it and take benefit in code review process.

I have seen startup companies rapidly code and deliver things to market with not so secure API’s and things like that can ruin the organization.
